Abstract

The invention discloses a magnetic induction water-proof encoder, which comprises a shell, a rotatable magnet assembly, a revolving shaft, a second magnet and three Hall elements, wherein the center of a shell cover is provided with an axle seat; a concave cavity which is coaxial with the axle seat is formed in the center of a shell bottom; an installation groove is formed in the outer side wall of the concave cavity; the rotatable magnet assembly is arranged in the shell; the revolving shaft is arranged in the axle seat; one end of the revolving shaft is connected with the magnet assembly; the second magnet is arranged in the concave cavity at the shell bottom, and is contacted with the revolving shaft through a thimble; two of the Hall elements are arranged on a circuit board below the shell; and the other Hall element is arranged in the installation groove at the shell bottom. The encoder has a simple structure, is low in cost, has a switch function and excellent waterproofness, and can work safely and stably in a damp or water spray environment.

Description

technical field [0001] The invention relates to a coding device, in particular to a waterproof coding device which converts angular displacement into a coded digitized electric signal, and has a switch function at the same time, and can output a switch signal independent of the coded signal. Background technique [0002] An encoder is a sensor device that converts angular displacement or linear displacement signals into encoded digital electrical signals. The former is called a code disc, and the latter is called a yardstick. According to the readout method, the encoder can be divided into two types: contact type and non-contact type. The contact type adopts the brush output, and the state of the code is "1" or "0" when the brush touches the conductive area or the insulating area; the non-contact type accepts the sensitive element is a photosensitive element or a magnetic sensitive element, and when the photosensitive element is used, the code is "1" or "0". The light-tran...
